My apologies! I just realized I grabbed the wrong series metadata. I had loaded both an MR and a CT for this patient and misremembered which one had the irregularity error message. It was the CT which was warned as irregularly spaced. Here is the image position patient data for that image volume: IrregularImagePositionPatientExample_CT.txt - Google Drive
@pieper, to your question about whether it is a rotated volume, this is the volume information
If I understand where you are coming from correctly, yes, this is a rotated volume because the IJK to RAS directions are not exactly aligned.
